never powerwash your engine, like stated about, you can force water into places water is not suppose to be, a water itself isnt a bad thing, but when u use a powerwasher it creates too much force and can work its way into places that can really give you electrical problems.

my advice is to stay away from the easy fix and spend some time one afternoon using some elbow grease, there is a good FAQ in the FAQ forum on a good way to detail the engine bay.
